Hello dear... Chest pain and rapid heart rate can be caused by various reasons, including minor problem such as indigestion or stress, to serious medical emergencies such as a heart attack. So, investigations like an Electrocardiogram or Stress Echocardiography can be done to rule out any heart involvement. Other causes of chest pain include: 1. Strained chest muscles due to overuse 2. Chest muscle injury 3. Short-term, sudden anxiety with rapid breathing 4. Peptic ulcer disease 5. Pain from the digestive tract, such as esophageal reflux So, it will be better to consult a Doctor & get a physical examination done to rule out other causes. So that proper management steps could be taken. Wishing you a Good Health. Let me know if I need to clarify further. Thanks & take care.
